(WASHINGTON) -- Despite nutritional labels on food and drinks, most of us have no clue how much we're actually consuming, according to a new study from the Food and Drug Administration.
The agency says most people don't accurately calculate what makes up a serving size.
For instance, take a bag of chips. If one serving of the snack has 90 calories, and there are 10 servings in a bag, how many chips is that exactly? Guessing the serving size may be confusing for many and could lead to people consuming more calories than they think.
To remedy that, the FDA is suggesting that labels should be modified to reflect the values for a full container. So instead of that bag of chips showing 90 calories per serving on its label, it would show 900 calories per bag.
